ZOZEN has built six fully automatic lines for the production of convection pipe, coil pipe, threaded pipe, membrane wall, serpentine tube and header. The parts so produced have consistent dimensions that enable easy assembly and ten years’ extension of a boiler’s life.

Seven hold points are set and each one is supervised by a responsible inspector. Any work that fails to pass the inspection cannot proceed until the inspector is able to verify its quality.

We use a great variety of automated and digital equipment, keep substantial stock of semi-finished products and maintain reliable relationship with our suppliers. As such, we are able to deliver packaged boilers within 30 days.

ZOZEN's main products include industrial boilers, power station boilers, waste heat recovery devices (HRSG), special waste heat boilers, pressure vessels and other five series with more than 400 varieties of specifications, mainly classified as: 10 ~ 220 t/h series power station boilers; SHL series bulk coal-fired Steam and hot water boilers; SZL series pipe assembly boilers; DZL series shell boilers; WNS series, SZS series of oil/gas fired boilers; YLL series of coal-fired thermal fluid heater; YYW series of fuel gas thermal fluid heater; biomass fuel boiler steam and gas combined cycle waste heat boilers, special waste heat boilers and so on.

What Products Do We Have?

Customers have covered all sectors of the world. Over the past 30 years, more than 12750 customer cases have been accumulated.

(Above) Class H16 No 30520 was photographed at Clapham Junction during the 1950s. At this time the H16s were regularly employed on Clapham Junction-Waterloo empty stock duties and in their final years Nos 30516 and 30517 found regular employment on the Fawley branch oil trains.

Alexander Ross, the Civil Engineer, was involved and many of the designs were dismissed as either being too heavy or too long. The MR compound type offered by R. Stephenson was dismissed by Ivatt as lacking sufficient power, and Oliver Bury persuaded the Board to accept the Vulcan 4-4-2 design, and this required modification to meet GNR requirements.

The Mount Washington Cog Railway, also known as the Cog, is the world's first mountain-climbing cog railway (rack-and-pinion railway). The railway is still in operation, climbing Mount Washington in New Hampshire, USA.It uses a Marsh rack system and one or two steam locomotives and six biodiesel powered locomotives to carry tourists to the top of the mountain.

A steam locomotive is a type of railway locomotive that produces its pulling power through a steam engine. These locomotives are fueled by burning combustible material – usually coal, wood, or oil – to produce steam in a boiler. The steam moves reciprocating pistons which are mechanically connected to the locomotive's main wheels (drivers

GWR KING CLASS by Derek Dean Maybe it now sounds simplistic, but the natural progression in steam locomotive lineage terms, following the most excellent 'Castle' class was a longer, larger beefed-up engine that was capable of hauling heavier trains at faster speeds.

Build a real head of live steam in the boiler, ease the throttle open and watch the engine take off. The stationary steam plants have nickel plated brass horizontal boiler, water gauge, whistle, safety valve, throttle, 3; dia flywheel and power takeoff pulley.

1 Maximum Steam Temperature obtained from production models; includes the use of superheaters. 2 Time from a cold start to reach maximum operating temperature. 3 Capital Cost per Kg of Steam calculated by dividing device output by device cost. Similar magnitude output devices are used. Prices used in calculations are general estimates obtained from public sources.
